PHOTO RADAR SENSOR DESIGN

OPERATION PRINCIPLE

The system automatically measures speeds of all vehicles in enforcement zone and records a pair of images for every captured vehicle: wide-angle image of all targets within the camera field of view (with the captured vehicle clearly identified), and a close-up image of the captured vehicle with clearly visible license plate.

The violation data includes the recognized license plate number, measured speed, type of violation (speeding, roadside driving, bus lane driving or driving in wrong direction), movement direction, date and time of violation, speed limit for current road section, name of controlled road section, geographical coordinates, sensor serial number. The system concurrently measures and captures all targets travelling in both directions within the controlled area. The principal feature – license plate recognition is performed throughout the whole controlled area. The archive of video clips and recorded violation data is simultaneously saved to internal storage and can be transferred to Police back office through secure wired or wireless communication lines for further processing.

INSTALLATION OPTIONS

The system has various installation and power supply options which may be used depending on tasks and technical capabilities on desired installation places.

STATIONARY

The system is installed at height of up to 10 meters using the mounting bracket on any lighting pole or similar support. The power comes from 110-220 V mains supply. The installation may take place either above the road or on the roadside.

MOBILE

The system is installed on a tripod at height of about 1.5 meters (breast height) at the roadside. The system is powered from battery box placed near the tripod and can be quickly transferred to another installation place.

POWER SOURCE

The system is installed on the roadside at height of 3-5 meters using the mounting bracket on any lighting pole or similar support. The mains power supply is not required, as the system is powered by replaceable battery in tamper-proof housing.
